Sew 2 lines of squares together. Now you’ll have 2 large pieces of 2×3 squares.
Then sew the sides to have complete it.
Now we just need to add the elastic! Sew the elastic’s sides together to have a circle.
Since the elastic circle will be smaller than the fabric one use pins to fold little pieces of the skirt in order to fit inside of it. Then sew the elastic.
Finally fold the bottom and set it!
